This is a really nice pair of Seneca Outdoors hike & trek sock in a hunter green color. They are knee high and made of 63% acrylic, 23% nylon, 12% wool and 2% elastic. A very sturdy and high quality sock. I have them listed under women's but they are actually a uni-sex item. For this sock size 10 - 13, it would be a women's 11-12 shoe size and for a man it would be 8 1/2 - 12 1/2 shoe size (according to label). Nice color and very nice feeling fabric. NWT.
